148 ALPS protocol version 3 has three different packet formats. The first two are
152 The first type is the touchpad position packet.
161 Note that for some devices the trackstick buttons are reported in this packet,
164 The second packet type contains bitmaps representing the x and y axes. In the
166 given axis. Thus the bitmap packet can be used for low-resolution multi-touch
167 data, although finger tracking is not possible.  This packet also encodes the
177 This packet only appears after a position packet with the mt bit set, and
181 The final v3 packet type is the trackstick packet.
193 Protocol version 4 has an 8-byte packet format.
204 The last two bytes represent a partial bitmap packet, with 3 full packets
205 required to construct a complete bitmap packet.  Once assembled, the 6-byte
206 bitmap packet has the following format:
218     identify the first fragment of a bitmap packet.
221     the packet layout is different.
229     the count of contact points can only be updated every third packet as
236 This is basically Protocol Version 3 but with different logic for packet
241 For single-touch, the 6-byte packet format is:
262 For trackstick packet, the format is:
271 For touchpad packet, the format is:
285 For trackstick packet, the format is:
294 For touchpad packet, the format is:
